INLINE COMMENTS
  src/main/java/org/apache/hadoop/hbase/master/HMaster.java:311 OK I can start 
with 1 instead of 0
  src/main/java/org/apache/hadoop/hbase/master/HMaster.java:314 I don't think 
it is necessary here.
  Because the coreThreadNumber is 0.
  Every thread launched by this thread pool is not from core pool.

> When one region server goes down, the master will shutdown the region server 
> and split its log.
> However, splitting log is a blocking call and it would take some time.
> If more than one region server go down, the master will split its log one by 
> one, which is not efficient.
> Since we have the distributed log split, we could split these logs from the 
> dead servers in parallel.
